Item # 1 may be as simple as updating your FRUSDR so that it would provide the correct sensor data records for the fans that are installed on the system. The firmware updates can be found here.

Item#2, on the TPS, there is a good read on how to populate memory on the server board on section 3.2.4.1 (page 21) as well as requirements for memory use. Also, check if it against the tested list available here.

Item#3, depending on how you configured your storage device, you may need to install additional drivers.
